Struct CpuCoreSet

Source

pub struct CpuCoreSet { /* private fields */ }

Expand description

Abstraction for CPU core set

Implementations§

Source §

impl CpuCoreSet

Source

pub fn cpu_cores(&self) -> &[usize]

Get cpu core numbers in this set

Source

pub fn truncate(&mut self, num_cores: usize)

Will truncate list of CPU cores to this number.

Truncation will take into account L2 and L3 cache topology in order to use half of the actual physical cores and half of each core type in case of heterogeneous CPUs.

If cores is zero, call will do nothing since zero number of cores is not allowed.

Source

pub fn pin_current_thread(&self)

Pin current thread to this NUMA node (not just one CPU core)
